Avoid acceleration-braking, find the right gear ratio, adjust your air conditioner…Here are some tips for fueling less in the car.
Switch off your engine during a prolonged stop.
Traffic jams are one of the most harmful situations for an automobile from an environmental point of view. A stationary car or stuck in traffic pollutes and consumes a lot. The engine heats up and pollutant emissions and fuel consumption increase.
When you expect the wait to last longer than a minute or two, turning off the engine will allow you to reduce your emissions and your consumption. This is also the principle of “start and stop” on modern cars.
